Hou Qi 0e7a485528 v4l2: Add protection when set decoder capture fps accroding to output fps 
Some v4l2 drivers don't have the capacity to change framerate. There is
chance to make decoder capture fps to be 0/0 if numerator and denominator
returned by G_PARM ioctl are both 0. It causes critical warning
"passed '0' as denominator for `GstFraction'".

In order to fix this, add protection when set decoder capture fps according
to output fps.

Hou Qi 5e932395a4 v4l2object: Add interlace-mode back to caps for camera 
skip_try_fmt_probes is set to TRUE for v4l2src to skip interlace-mode and
colorimetry when probe caps. gst_v4l2_object_set_format_full() will add
colorimetry back to caps when iterating over the negotiated caps. There is
one case that v4l2src is first in preview state then starts recording.
v4l2src caps will change with an additional interlace-mode structure after
renegotiation, then v4l2src needs to reset. But this camera driver can't
orphan buffer pool, it causes require buffer failed as streaming is still
in active state.

To fix this, also need to add interlace-mode back to caps for camera to
avoid reset.

Tim-Philipp Müller c70b41b22b v4l2: fix debug category initialisation again 
Would spew warnings on the rpi4 when calling into
gst_v4l2_object_get_codec_caps() from the probe_and_register()
function since the v4l2_debug category initialisation would
only be done later as part of the element/device provider
registration.

Also log things in the probe function to the v4l2 category
instead of the default category while we're at it.

Hou Qi a75cfa522d v4l2object: Use default colorimetry if that in caps is unknown 
Some streams have unknown colorimetry in caps, but v4l2object sets
default values for each primaries. It will cause check colorimetry
fail when do gst_v4l2_video_colorimetry_matches().

To fix this, need to keep the unknown colorimetry in caps same as
the default value set by v4l2object.

Hou Qi e037391364 v4l2object: Avoid colorimetry mismatch for streams with invalid colorimetry 
video-info sets gst colorimetry to default value when colorimetry in caps
is unparsable or invalid. Then v4l2object uses this gst colorimetry to do
mapping with v4l2 colorimetry. This may cause colorimetry mismatch when
check mapped gst colorimetry with that read from caps directly.

To fix this, need to correct gst colorimetry as that parsed from video-info
when check gst_v4l2_video_colorimetry_matches().

Hou Qi fc5a1e468b v4l2videodec: Do not expose profiles/levels in vp8/vp9 template caps 
Vp8/vp9 supported profiles/levels are listed in decoder sink caps, but
there is no parser for these two formats and the demuxers also don't have
these information. It causes negotiation fail between demuxers and decoder
when check caps "accept = gst_caps_is_subset (caps, template_caps);".
To fix this, need to remove profiles/levels for vp8/vp9 formats in decoder
sink caps.

and ::fps_d fields to 0.
To fix this, copy the frame rate from the sink side.
